It's "boolean", not "bool" in JVM speak.

This looks odd to me. "L" marks the beginning of an class name and
it's terminated by ";". You could just strhchr() the terminator and
simply copy the name to "buf" and drop cases ';', '/', and the default
label fro the switch statement.

Truncated symbols are lame. Can't you use realloc() to ensure that
never happens?
